Extended protection embolic filter

摘要

The disclosure pertains to porous embolic debris diverters comprising a porous diverter element, a support structure therefor, and a non-hollow flexible elongated retrieval element fixedly attached thereto. The disclosure further pertains to delivery systems for the embolic debris diverters comprising a pusher and an elongated sheath as well as methods of use for the porous embolic debris diverters and the delivery systems therefor. The porous embolic debris diverters are adapted to remain within the body for extended periods of time.

主权项

1. An embolic protection device comprising:
a porous diverter element having a distal opening; a support structure connected to the distal opening of the porous diverter element; and a non-hollow flexible elongated retrieval element having a distal end and a proximal end, wherein the distal end is fixedly affixed to at least one of the porous diverter element and the support structure and the proximal end is adapted to remain outside of the body, further wherein the embolic protection device has a first compressed state and a second expanded deployed state wherein the distal opening of the porous diverter element does not form a closed loop, and wherein the support structure includes a partial loop supporting the distal opening of the porous diverter element.
